The Thai stick I grew in the 80s was fickle as hell very long flowering think 120+days the bugs were long but thin perhaps with all of today's tech I could do better maybe the strain around these days is not as demanding
"Thai sticks" from what people have told me were local bud soaked in opium and wrapped with string. I've never even seen one of those.
I've definitely heard of tropical sativa strains that run over 15 weeks and were said to be all but psychedelic so what you're saying rings true to me.
One of the things our current breeding and selection craze has definitely done is basically get rid of anything that takes longer than 70 days to finish. No one wants to wait anymore. In large part it's because time is money in a growroom and the longer a strain runs, the more it costs to grow- and yet no one wants to pay the premium for such a product.
I've had people turn down my Hillbilly Hobby just because they're scared of the 9th or 10th week. All ya gotta do is stick it in a few days early and then pull it last for trimming!
